■Watetsu products made from Tatara iron-making At Okuizumo area in Shimane prefecture, “Tatara iron-making” method to make Watetsu (Japanese iron) had much developed since almost 1400 years ago, using local iron sand and charcoal. 13 ton of each material are used for just one operation that continues for three days and nights. Finally 3 ton of ingot called “kera” is left. Its best part is “Tama-hagane” which was used as the main material of Japanese swords. After Meiji period (around 1900’s), the western technologies, using iron ore in a blast furnace, drove out Tatara. The Tanabes, an established local family used to be a leading iron-making master for about 550 years, attempted to resurrect Tatara and made it into relaunching in May 2018. These products, mainly kitchen knives, are all made from Watetsu, including Tamahagane. This is the first exhibition and sale of the products outside Shimane prefecture.
